Review: Well designed and great to use - I ordered this trimmer after finding battery trimmers at Lowes hardware store. I had not realized that motor and battery technology had improved to such a degree as to make such a product viable. I don't buy much these days without checking reviews and this product was rated highly by many consumers (>250). The $99 blower and trimmer in Lowes was not worth the money in my opinion and a U-Tube video on the Kobalt product was not convincing especially at $150 + tax. I forgot to add the additional two years of warranty when I first ordered the machine so I cancelled the first order and added the extra 2 years of warranty which was about $9. desertcart was good enough to ship the second order for the same delivery date. There was a B&D promotion also and desertcart took care of that for me also since it did not show up at checkout ($10 off). desertcart support is excellent in my opinion. When the trimmer arrived I put it together immediately in about 5 mins (A handle and the guard, that was it). The battery had some charge in it so I took it for a trial run. I was impressed with the full power torque but I reduced the current by taking the adjustment down from the "9" setting to the "2" setting and it worked just fine. There is a simple adjustment for the length of the trimmer shaft and I soon started trimming. I had not realized that there was very little charge left but I still got down one side of the house before the battery started to fade. The battery charged fully in about an hour or so. The motor turns to make edging easier and there is a wire guide to make edging easier. I'm very impressed with this product so far although I have not yet put it to the test with a fully charged battery (1.5 Ah). I am delighted with the weight also and after bruising my fingers trying to start my 2-stroke trimmer I am convinced this is the way to go. The battery is very solid and has an easy way to latch and remove. Also, the battery has three indicators with a test button so that the charge can be checked. At some point it may be worth getting the larger battery (2 Ah) but for now I'll see how it goes. The batteries are warrantied for 3 years. This trimmer has a single string and after fiddling with a dual-string machine replacement spool I am very happy with the single string. It does not appear to affect the performance of the trimmer at all. I'm hoping the string advance is working as stated, time will tell. I have a purchased a number of Black and Decker products (e.g., hedge trimmers, drills, drill press) and I have never been disappointed. I still have the products and they still work well after many years of use. They sell good quality and well designed products at a very reasonable price. I'm glad they're still in business. I will likely continue buying their products because of the excellent price/performance ratio they provide. Of course I always come to desertcart to make the final purchase. Why go anywhere else? Day 2 I trimmed around the house and I had 1 green light left on the battery so I stuck it in the charger. Still happy with the product. The string failed to auto feed at one time so I had to pull off the string cover to get it to about a 4" length which meant pulling out the spool and making the adjustment. It's important to have the line wrapped evenly for the auto feed to work well. Practice makes perfect as they say. I did find I had to adjust the handle grip to suit my height but that's expected. It slides very easily up and down the shaft. The battery LEDs are very handy. Pay attention to removing the battery when you adjust the head (see the manual) as a safety precaution.
Review: Huge improvement over 18V model! - I have been using the 18V version of this trimmer for about 10-12 years and have been reasonably happy with it. It did not quite have the power of a gas trimmer but it did the job with far less hassle than the gas trimmers we had been using. The biggest drawback to it was the battery consumption. I have an acre property, with about 120 feet of driveway with lawn on both sides. Edging the driveway alone required more than one battery. trimming around the half-acre of fenced backyard and various backyard objects (kids swingset, grill, etc) would require more than one battery. In all we needed 3 batteries to get through all our trimming and edging needs, and sometimes (not often) we would use up all 3 before getting it all done. We had to take care to get the most important parts done first just in case, and go back out after a battery recharge to complete the job. When the 18V batteries began to fail I went looking for replacements and came across this 40V model and based on other reviews I decided to give it a try, and I can say I am extremely happy! The trimmer itself is mostly the same as the 18V model with the exception of the power control. More on that later. It uses the same line spool so I was able to use the line we already had on hand, and save a couple of parts from the spool head of the old model for later use. The two features that really set this apart from the old model are Power and Battery Consumption. Firstly, the POWER: This model easily rivals the gas powered models I have used (admittedly not 'professional' grade models). With the power control set on 3 it gives me enough power to get that really sharp edge on the driveway that the 18V model simply could not. With the power control set to 1 I still have sufficient power to trim around the fence line and other objects. Occasionally I will set it to 2 to get through some weeds or to trim a larger area of grass where the mower doesn't fit. The biggest advantage to me however, is that this model gets through everything I need it to do with just ONE battery, and with power to spare! The power meter on the battery still has 2 of its 3 status lights on when I am done. There are some reviews on the replacement 40V battery which point to the lack of a cut-off circuit on the trimmer to protect the battery, and this is true. The trimmer will not cut off automatically when the battery is low, and this can be a big problem for a Lithium Ion battery of this type since this type of battery will suffer irreparable damage if it is drained below a certain point. Care must be taken not to allow this to occur. As I mentioned previously, this model is able to complete all the work on one battery that the previous model needed 3 to perform, and has power to spare, so the first thing to know is you should ALWAYS recharge the battery after every use, even if you use it only a few minutes. A small charge will not damage this type of battery, there is no 'memory' effect with this battery type. It also is not a problem to leave the battery on the charger between uses. Secondly, keep a careful eye on the battery power meter when using it. There is a small button next to 3 LED lights. Push the button and the lights will indicate the battery state. When only one LED lights, you can still continue to work but check the battery state even more frequently and STOP as soon as no lights come on. Continued use below this battery charge state may cause the battery to fail prematurely. Such failure is likely to be complete, meaning the battery will no longer take any charge at all. This is typical of Lithium Ion batteries and is not a manufacturing fault. Thirdly, use only as much power as you need. The power control has settings of 1-6. The higher the power setting, the lower the runtime you will get from a battery charge. As stated previously I use 3 for edging on my driveway and 1 for regular trimming. I have not had a need to use a setting higher than 3 but I have no thick weeds to trim. Some other reviewers have complained about the string feeder using too much string. This may be true, I have not personally compared the usage with a bump feed trimmer, but I can say the feed mechanism works much more reliably than the bump-feed mechanisms I have used in the past. It is a very simple mechanism, just a single moving part which is replaceable. The cap which holds the spool in place will wear out after a few years. After all it is spinning and does at times accidentally make contact with the ground. It is easily replaceable and is not expensive. I have not found the string usage to be a problem. I think overall, when one compares the cost of the gas+oil plus the bump-feed string usage of a gas powered trimmer with the cost of electricity to charge the battery plus the cost of string, I suspect this model still comes out ahead and it wins hands down in convenience and ease of use. Update 8/30/2017: After a year and almost through our second season with this, I am still very pleased with this product. It still gets the job done on a single battery with power to spare and I've had no issues with it whatsoever.

### ⭐⭐⭐⭐⭐ Huge improvement over 18V model!
*by S***M on June 23, 2016*

I have been using the 18V version of this trimmer for about 10-12 years and have been reasonably happy with it. It did not quite have the power of a gas trimmer but it did the job with far less hassle than the gas trimmers we had been using. The biggest drawback to it was the battery consumption.

### ⭐⭐⭐⭐ The battery failed after just 2 charge cycles
*by C***Y on April 22, 2015*

** UPDATE, APRIL 28 ** After tracking down a way to contact the right person in Black & Decker Customer Service, I have to update my rating and revise my reveiw. Much to their credit, they made good and the replacement battery arrived today. OK, so I already bought a replacement and handed over another $80, but maybe it's a good idea to keep a spare handy anyway. Other than the issue I had with the battery, which has now been remedied, I really like the trimmer. It's not too heavy, it's pretty powerful, and it's a lot quieter/cleaner than my old 2-cycle gas engine beast. It's good for a homeowner with reasonably sized yard. Thank you Black & Decker for restoring my faith in Customer Service and replacing the defective battery without a challenge. ** UPDATE, APRIL 24 ** : For now I will increase it from 2 to 3 stars and maybe more later. After a few unsuccessful frustrating attempts to contact Black & Decker Customer Service by phone I used the email option and explained as below that the battery had failed after just 2 charges. Today I received a reply from Laurett in B&D Customer Care apologizing for in inconvenience and indicated they would be sending a new replacement battery and I should receive it within 7 business days. Now that's more like it! (I guess after so many miserable experiences with the unrelated to this episode but inappropriately named Comcast Customer Service, I had become cynical and lost my faith) If I really get in soon and it works I'll add another a star since I really do like the trimmer and it's performance a lot. It was just a battery issue. Bravo to Black & Decker for making it right! Since I already bought a new battery and charged it I'm stuck with two now, but that's OK since it's probably good to have a spare. _______________________________________________________ I purchased this string trimmer in June. It was fairly light, easy to handle, and worked exceptionally well for the rest of the season. The battery only required a charge twice the entire season, however the battery soon became a big headache. As fall came I removed the battery and kept it indoors for the winter rather than in the tool shed. A friend had advised that I do this claiming that lithium batteries should not be exposed to freezing temperatures for extended periods of time. Last week as spring finally arrived and the lawn needed attention I put the battery in the charger, however it would not take a charge and a red indicator light on the charger was blinking indicating a defective battery. Black & Decker customer service has not been helpful at all and I was advised to purchase a new battery. I have ordered one, however a new replacement battery cost me almost $80! The entire string trimmer new cost less than $150! I find it hard to believe that more than half of the cost of the trimmer is in the battery. A battery that was very well cared for and only had 2 charge cycles on it should not fail in the first place. I cannot recommend this trimmer regardless of how well it works when the battery is functioning.
